Paleogeography and Quaternary geomorphology

Landscape evolution through glacial and interglacial periods is a classic subject of geomorphologic studies. The Geocryolab takes great interest in environment successions during these stages, from glacial to marine transgressive to periglacial or temperate. The successions and how they operate have a great impact on surface deposit spread and on permafrost properties. This approach allows for a thorough understanding of permafrost inception processes, leading to the possibility of predicting and explaining soils rheological and cryogenic conditions.

Since frost and permafrost are potent natural freezers, permafrost degradation at times reveals environmental relics dating many thousand years. Buried glacier ice, organic matter such as pollens or macrorestes and paleosols found in perennially frozen grounds can provide information on past climatic conditions. The data extracted can be used to model environmental responses to climate changes.
